LUBRICATOR.

To all whom it may concern:

Be it known that I, VTILLiAM L. NEW- BAKER, a resident of l/Vilkinsburg,in the county of Allegheny and State of Pennsyl- Vania, have inventedcertain new and useful Improvements in Lubricators, of which thefollowing is a specification.

The primary object of this invention is to provide an improvedlubricator for dispensing oil only when the engine or other machine uponwhich it is mounted is in motion.

A further object is to provide for agitating the oil so that the samepasses from the holder freely and without clogging.

Still a further object is to provide for the control of a series of oilports or passages by a single valve mechanism which operates to admitoil to the several ports only when the machine to which the lubricatoris applied is 111 motion.

Still a further object is to provide improved means for intermittentlyoperatingv the lubricator valve.

In the accompanying drawings, Figure 1 is a side elevation of thelubricator, and Fig. 2 a vertical central section. Fig. 8 is a top plalnof the bottom member of the oil receptac e.

Referring to the drawings, the oil receptacle is preferably oftransparent oil-cup construction, and consists of bottom member 2, topmember 3, and the glass tube or cylinder 4 sealed between the top andbottom members and secured by the clamping rods 5.

Extending downwardly from bottom member 2 is the threaded supportingextension 6 which may be screwed into a cylinder, bearing, or other partof the machine or engine, of which a fragmentary part is shown at 7. Anoil discharge port 8 may open downwardly through bottom 2 and extension6, with the upper end of the port enlarged within the bottom surface ofthe receptacle, as indicated at 8. Port 8 may constitute the principalor cylinder lubricating port, as when the device is applied to anengine.

It is characteristic of the invention that a plurality of dischargeports extend out-- wardly from the bottom of the receptacle. As hereshown, these additional orts 9 open upwardly through a circular raisedsurface 10 on the receptacle bottom, with pipes or ducts 11 extendingoutwardly therefrom to Specification of Letters Patent.

hearings or other portions of the machine 01' engine requiringlubrication.

Within the receptacle is the plate-like valve neath the valve head andentered in -de-- pression 8 and the upper portion of port 8, therebyguiding the valve while moving vertically so that it cannot becomedisplaced. A spring 15 holds the valve normally depressed and seated onsurface 10, with the oil shut off from all of the ports. Stem 13projects upwardly through top member 3 and through the transversebearing slot 16 formed therein. Mounted to oscillate vertically in thisslot is lever 17 having an aperture in which the stem loosely fits, withlock nuts 18 clamping the stem and lever in the desired adjustment.

Various means may be provided for op erating lever 17. That here shownconsists of a link or rod 19 depending from the lever and adapted to beintermittently raised by a cam or knocker 20 on shaft 21. This shaft maybe driven by the engine or other machine to which the lubricator isapplied, or said rotating part may consist of any movable portion of theengine or machine. For each revolution of the shaft and its cam, lever17 is raised and with it the valve against the pressure of the spring,thus opening the several oil discharge ports. The backward orspring-return movement of the valve following the release of lever 17 bythe cam operates to shut off the oil from all of the ports, and at thesame time the action is such as to force or advance oil therethrough.The form of hearing at the upper end of the receptacle in connectionwith the loosely connectedlever provides for a certain and positiveoperation. The tension of the spring closes the valve instantly when therelease takes place. Thus, all the discharge ports are controlled by asingle valve which is normally closed, so that the lubricator isthoroughly automatic in its action and requires absolutely no attentionon the part of the operator.

While I have here shown and described the preferred embodiment of theoil receptacle and its discharge port-controlling valve, the ports maybe variously arranged and the valve may be variously constructed andoperated without departing from the invention.

I claim 1. In a lubricator, the combination of an oil receptacleincluding a member forming the bottom thereof, said member surfaced toprovide a valve seat with a plurality of oil passages opening upwardlytherethrough, the bottom member also formed with a depression, a valveadapted to engage the seat and close all of said passages, and operatingmechanism connected to the valve from above and projecting therethroughwith the projecting portion entered in said depression when the valve isclosed.

2. In a lubricator, the combination of an oil receptacle having acentral bottom depression with an oil passage leading from thedepression, the surface of the bottom surrounding the depression forminga valve seat with a series of oil passages opening therethrough, adisk-like valve seating on said surface for closing all of the passages,and valve operating means.

3. In a lubricator, the combination of an oil receptacle having acentral bottom de pression with an oil discharging port leading from thedepression, the bottom having a fiat surface surrounding the depressionwith oil-discharge ports opening through said surface, a valve having aflat under face seating on the flat surface, a stem for the valveextending into the central depression, a spring for opposing upwardmovement of the valve, and valve opening means.

4. In a lubricator, the combination of an oil receptacle having acentral bot-tom depression with an oil passage leading from saiddepression, the bottom having a surface surrounding the depression witha series of discharge ports opening upwardly therethrough, a valveseating 011 said surface and shutting ofi the oil from all the ports, aspring for opposing upward movement of the valve, and valve openingmeans.

5. In a lubricator, the combination of an oil receptacle having adischarge port, a vertically movable valve within the receptacle fornormally closing the port, the valve having a stem projecting upwardlythrough the top of the receptacle and the latter formed with atransverse slot through which the stem extends, a rocking lever mountedto oscillate in the slot and loosely connected to the stem, a spring forholding the valve normally closed, and means for actuating the lever toopen the valve against the pressure of the spring.

In testimony whereof I aflix my signature in presence of two witnesses.
